[Merge to XFA] Revert "Revert "Add type cast definitions for CPDF_Dictionary.""
This reverts commit 937840e1722d1f2b77d80575d6e710d760662c9c. Add type cast definitions for CPDF_Dictionary. This CL adds ToCPDFDictionary type definitions and updates one file to use instead of straight casts. I had to fix two places where we'd casted off the constness of the original pointer. BUG=pdfium:201 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1420583003 . (cherry picked from commit 39869b641511c882d78e17548293cdb458c36f38) Review URL: https://codereview.chromium.org/1410343003 .
